Interphase Announces First Quarter 2012 Financial Results

PLANO, Texas – April 26, 2012 -- Interphase Corporation (NASDAQ: INPH), a diversified information and communications technology company, today reported financial results for its first quarter ended March 31, 2012.

Revenues for the first quarter of 2012 were $4.0 million, a decrease of $2.7 million when compared to revenues from the first quarter of 2011 of $6.7 million.  On a sequential basis, revenues increased approximately 11% from $3.6 million in the fourth quarter of 2011.  Revenues in the quarter were primarily derived from telecommunications and enterprise product revenues, which decreased to $3.2 million in the first quarter of 2012 compared to $6.3 million for the first quarter of 2011.  Services revenues increased approximately 114% to $781,000 for the first quarter of 2012 compared to $365,000 for the first quarter of 2011.  Gross margin was 46% for the first quarter of 2012 compared to 49% for the first quarter of 2011.  The decrease in gross margin percentage was primarily due to decreased utilization of the company’s manufacturing facility partially offset by a shift in product mix toward higher margin products and services.   The company reported a net loss of $929,000, or ($0.13) per share in the first quarter of 2012 compared to a net income of $231,000, or $0.03 per fully diluted share in the first quarter of 2011.  On March 31, 2012, the company’s working capital position was $13.7 million, including cash and marketable securities of $10.7 million.

 “Although we achieved 11% sequential revenue growth this quarter, these results provide additional support for our strategy that we have been emphasizing for more than two years, to build a more diversified company that is less dependent upon a single market and small group of customers for our success,” said Gregory B. Kalush, CEO and President of Interphase.  “On April 18, 2012, we took a big step toward executing on this diversification strategy as we announced the debut of penveuTM, a disruptive interactive presentation device that radically evolves the industry by enhancing the functionality of installed projectors and large screen displays.  We believe that penveu will be a very strong new entrant into the market for interactive display technologies that includes the $1.8 billion interactive white board market. We plan to commence shipments of penveu in July.”
